You missed a few alternatives. I've added them myself, and ran the benchmark again.
I must say that they perform rather poorly.
Benchmark::cmpthese(0, {
split => sub { @data = split(/\s+/, $line) },
fixed_length => sub { @data = $line =~ /^.{8} {6}(.{10})(.{10})(.{1
+0})(.{10})(.{10})(.{10})(.{10})(.{10})(.{10})(.{10})(.{10})(.{10})$/
+},
var_length => sub { @data = $line =~ /^.{8}\s+(\S+)\s+(\S+)\s+(\S
++)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)\s+
+(\S+)$/ },
g => sub { @data = $line =~ /\S+/g; },
unpack => sub { @data = unpack 'A8x6A10A10A10A10A10A10A10A10A
+10A10A10A10', $line }
});
Result:

You ignore the first field, I include it... but that shouldn't matter much.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
